Hi all,

I have a file whose content I need to read and get the 3rd line .. ex:

Code:

one
two
three

jaduks · #2 (**permalink**) 05-17-2008

Code:

$ cat test.txt
one
two
three

$ sed '3!d' test.txt | cut -c1-3
thr

Might as well do it all in sed.

Code:

sed -n '3s/\(...\).*/\1/p' test.txt

Era's solution helped me to find two more similar ways . Thank you Era.

Code:

$ sed -n '3 s/\(.\{3\}\).*/\1/p' test.txt
thr

$ awk 'NR==3 {print substr($0,1,3)}' test.txt
thr
